The last issue with Unit crash should be fixed with this patch:

Obviously, your app cannot start after ruby uninstall.
Regarding your question
why app start for root ruby only?
I guess root ruby is a ruby 2.5 (please confirm). Application 'football' failed to start because of missing file during it's load. If you expected application 'football' uses ruby 2.6.3 environment (please confirm), then your Unit ruby module should be built against proper ruby version. I guess you are using Unit from packages (please confirm) and packaged ruby module built for ruby from Ubuntu repository. To use newer version, please follow Configuring Ruby documentation instructions.
Your experiments with sudo can be demystified by the fact sudo lookups ruby binary using it's own PATH variable. Compare: $ echo $PATH with $ sudo bash -c 'echo $PATH'.
